. IE. :1 I NVENTOR 76;,ATTORNEY5 PATENT Be it known that" we, ALLEN? H.--HUeHEs. and HAROLD -OURREN, citizens... offlthe UnitedStates, and residents of Rochester,

\ in the countyof Monroe and State of New- York, have invented certain new. andnseful Improvements-- :in';: Holding Means 'ifor: Clutch-Levers,- of which the following a,

specification. i

larly to, the type .of .clutchleverspzin which the clutch lever has a tendency to remain in clutching position, an object of this ainvention being .to provide a holdingmeans which. may. be readi1ymoved==to detaining; position for holding the clutch lever in=u-n-=v clutching position and which will upon pressure uponlthe clutch lever, automatically move-away: from adetaining position. Still another object of the invention is to provide a clutch lever which may be readily mounted upon the tractor known commercially as the Samson tractor.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Figure 1 is a fragmentary view of a'tractor known commercially as the Samson tractor, one of the wheels of the tractor being removed for the purpose of showing clearly the mounting of the holding means;

Fig. 2 is a detail side view of the holding .means removed from the machine; and

Fig. 3 is a detail plan view of the holding means.

In the tractor known commercially as the Samson tractor, a band wheel 1 is provided which is driven from a motor inclosed within the casing 2, a clutch being provided in said casing and being controlled by a lever 3 on the exterior of the casing mounted on a rock shaft 4 connecting with the clutch. This lever at the same time has an extension 5 cooperating with 'a'lever 6 which applies a brealdng element 7 to the inner pc- Application and much 27, 1920. seriaino. 369,185.

'ra i 1I In: the iuse of this machine, it is desirable at: times to hold the clutch lever 3- depressed independently of: a foot on the' treadlefportion-18 and to this 'end,=1adetaini ng means is provided which comprises a lever 11' pref- 4 q erably-of'bell crank formation pivoted at 12 Thev present invention relates to. holding means for; clutch levers and more particuat a poinflabove the lever 3 andhaving onearm notched+at 13, so asto engage with the upper. surface/of the lever 3,- its other arm extendediupwardlyi so thatthe one seated uponthe seat l-fmay by- -foot pressure upon the zupwardly=i iextending arm; movethe notched portion :13' of thelower arm of the lever; 1 :11 into: engagement i with the clutch lever: 3 andi'b eyond the :dead center so that the action of the spring 9 will tend to holdthe: detent in detaining position Y until downward pressure is again applied to the clutch lever 3 whereupon the spring 15 will be brought into action and will shift the do taining lever to the dotted line position illustrated in Fig. 1.

The detaining lever may be mounted in in accordance with this invention is simple I in operation and inexpensive to manufacture; It is especially ada ted for use with a Samson tractor and e ectively holds the clutch lever in unclutching position. The release of the detaining member may be effected automatically by pressure upon the clutch lever.

What we claim as our invention and de-v sire to secure by Letters Patent is:

1. In combination with a clutch lever normally movable to clutching position, a detaining member pivotally mounted above the clutch lever to swing to one side of a dead center in order to hold said detaining member in detaining position, and a spring acting on said detaining member to move it to I the other side of the dead center in order to free the clutch lever upon a depression of such clutch lever while it is held taining member.

pivoted above said clutch" lever" and having two arms,,1 one projecting forwardly an movable downwardly into en agement with said clutch lever to holdthe-latter infiun-j clutching position,-and the other extending upwardlyw sto provide-an operating portion for s'uchv detaining member,- said; detaining member having a normal tendency to m'ove away from detainingpositionsothat' upon the depression of the clutch leveru-while the latter is, engaged by the detainingmember,
